PENGARUH PENGGUNAAN PUPUK ORGANIK CAIR URIN SAPI TERHADAP PRODUKTIVITAS FODDER JAGUNG

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan pupuk organik cair (POC) urin sapi terhadap produktivitas fodder jagung. Materi yang digunakan meliputi benih jagung, urin sapi segar, molases, EM4, dan air. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 5 perlakuan dan 4 ulangan, yaitu P0 = 100% air (kontrol), P1 = 20% POC urin sapi, P2 = 25% POC urin sapi, P3 = 30% POC urin sapi, dan P4 = 35% POC urin sapi. Variabel yang diamati meliputi tinggi tanaman, produksi biomassa, produksi bahan kering (BK), dan produksi protein kasar (PK). Data dianalisis menggunakan Analysis of Variance (ANOVA). Hasil penelitian menunjukkan bahwa pemberian POC urin sapi tidak berpengaruh nyata (P>0,05) terhadap tinggi tanaman, produksi biomassa, produksi bahan kering, dan produksi protein kasar. Meskipun demikian, perlakuan P3 (30% POC urin sapi) menunjukkan kecenderungan menghasilkan produktivitas yang lebih baik dibandingkan perlakuan lainnya, dengan rata-rata tinggi tanaman sebesar 28,84 cm, produksi bahan kering sebesar 18,30 ton/ha, dan produksi protein kasar sebesar 4,14 ton/ha. Sementara itu, produksi biomassa tertinggi diperoleh pada perlakuan P4 (35% POC urin sapi), yaitu sebesar 1,644 kg. Berdasarkan hasil penelitian dapat disimpulkan bahwa penggunaan POC urin sapi hingga konsentrasi 35% belum mampu meningkatkan produktivitas fodder jagung secara nyata, meskipun terdapat kecenderungan peningkatan pada beberapa parameter.

EFFECT OF COW URINE-BASED LIQUID ORGANIC FERTILIZER ON CORN FODDER PRODUCTIVITY

Abstract
This study was conducted to evaluate the effect of cow urine-based liquid organic fertilizer on corn fodder productivity. The materials used in this study consisted of corn seeds, fresh cow urine, molasses, Effective Microorganisms-4 (EM4), and water. The experiment was conducted using a Completely Randomized Design (CRD) consisting of five level treatments with four replications. The treatments were as follows: P0 = 100% water (control), P1 = 20% cow urine-based liquid organic fertilizer, P2 = 25% cow urine-based liquid organic fertilizer, P3 = 30% cow urine-based liquid organic fertilizer, and P4 = 35% cow urine-based liquid organic fertilizer. The observed variables included plant height, biomass yield, dry matter production, and crude protein yield. The data were analyzed using Analysis of Variance (ANOVA). The results showed that the application of cow urine-based liquid organic fertilizer had no significant effect (P > 0.05) on any of the observed parameters, including plant height, biomass yield, dry matter production, and crude protein yield. Nevertheless, treatment P3 (30% cow urine-based liquid organic fertilizer) tended to produce better productivity than the other treatments, with an average plant height of 28.84 cm, a dry matter production of 18.30 t ha⁻¹, and a crude protein yield of 4.14 t ha⁻¹. Meanwhile, the highest biomass yield was obtained in treatment P4 (35% cow urine-based liquid organic fertilizer), reaching 1.644 kg. Based on the findings of this study, it can be concluded that the application of cow urine-based liquid organic fertilizer at concentrations of up to 35% did not significantly improve corn fodder productivity, although an increasing trend was observed in several parameters.
